ST153: RAYCHARGE BACKPACK (RCB)

LEE WEI UNIT KOKURIKULUM

RayCharge is an innovative smart backpack designed to integrate energy storage and solar charging technology into a single, practical, and eco-friendly solution. It was developed in response to the increasing dependence on electronic devices such as smartphones, tablets, and laptops, which often experience rapid battery depletion especially during travel, outdoor activities, or in areas with limited access to electricity. Conventional charging solutions such as separate power banks and portable solar panels are often bulky, inefficient, and inconvenient to carry, creating the need for a more compact and user-friendly alternative. The main objective of RayCharge is to provide a reliable and sustainable energy source that ensures continuous device charging anytime and anywhere. The product aims to reduce user dependence on conventional electricity while promoting the use of renewable energy in daily life. The materials used include a durable waterproof nylon exterior, a flexible foldable solar panel, and a built-in rechargeable lithium battery with dual USB ports for multiple device charging. The method of development involved designing a backpack that combines aesthetic appeal with functionality, embedding the solar panel into the bag surface and connecting it to the internal battery through an intelligent power controller that manages solar energy conversion and storage efficiently. In terms of novelty, RayCharge offers a unique integration of fashion and clean technology. It transforms an ordinary backpack into a smart energy companion that provides comfort, style, and functionality simultaneously. Its portability, efficiency, and eco-conscious design distinguish it from existing products in the market. The innovation is applicable to students, travelers, professionals, and outdoor enthusiasts who require constant power access. With a production cost estimated at RM48 per unit, it is affordable and suitable for large-scale manufacturing. The commercial value of RayCharge lies in its ability to meet a universal need for portable energy while aligning with the growing global trend toward green technology and sustainability. The impact of this innovation extends to the environment, economy, and society by encouraging renewable energy adoption, reducing electronic waste, and enhancing safety during travel or emergencies. Supported by strong market demand and sustainability appeal, RayCharge has the potential for widespread commercialization both locally and internationally through retail, online platforms, and educational partnerships.
